Hazırlanışı
1Preheat the oven to 400°F. Position the rack in the center of the oven. Coat a 2-quart soufflé dish or 6 individual 8-ounce dishes with cooking spray. Coat with bread crumbs. Tap out excess; set aside.
2Fill a bowl with ice and water; set aside. Place a steamer basket in a large saucepan; fill with 1 inch water. Bring to a boil, and add the spinach. Cover, and steam until wilted, about 3 minutes. Drain, and plunge into the ice bath to stop the cooking. Let cool, and squeeze out excess water. Place the spinach in the bowl of a food processor; pulse until finely chopped; set aside. You should have about 1 cup.
3Melt the butter in a small saucepan over medium heat. Whisk in the flour, and cook, stirring constantly, for 3 minutes. Gradually whisk in the milk, and bring just to a simmer. Cook, stirring constantly, until slightly thickened, about 3 minutes. Stir in salt and pepper. Remove from heat, and set aside.
